What system environment stores the value of InetAddress.getLocalHost().GetCanonicalHostName()

Question

I try to understand which system variables has this value. I execute this code and get some_string .

InetAddress.getLocalHost().GetCanonicalHostName();

After this I print all my system env

System.getenv().forEach((k, v) -> System.out.println("K = " + k + " V = " + v));

I find all variables which has some_string , and replace all value with

@ClassRule public final static EnvironmentVariables ENVIRONMENT_VARIABLES = new EnvironmentVariables();

 final String pcNameForEnv = "test-pc-name"; ENVIRONMENT_VARIABLES.set("USERDOMAIN", pcNameForEnv);

But my test failed

@Test public void getMachineNameFromEnv() { final String pcNameForEnv = "test-pc-name"; ENVIRONMENT_VARIABLES.set("USERDOMAIN", pcNameForEnv); final String machineName = networkUtil.getPCNetworkName(); assertEquals(pcNameForEnv, machineName); }

I finded that I need replace this ver:

"user.name", "user.home", "LOGONSERVER", "COMPUTERNAME", "USERDOMAIN_ROAMINGPROFILE", "USERDOMAIN", "COMPUTERNAME", "MACHINENAME";

But it don't help me too.

You can't set an environment variable to make Java think you are on a different machine. From java.lang.InetAddress -

Returns the address of the local host. This is achieved by retrieving the name of the host from the system, then resolving that name into an InetAddress.
